Thanks FAL!
Yes, Autonovo OY was entrant of all works Fiats at 1000 Lakes, so it should be Finnish importer.
Do you possibly know the entrants of 1977 RAC for Fords of Waldegard-Thorszeluis, Clark-Pegg, Vatanen-Bryant & Hamalainen-Scott?
I believe these were the 4 works cars.
And for the one of Brookes-Brown the entrant was probably Andrews Heat for Hire?
